This invention relates to liquid fuel burning apparatus disclosed in my application Serial No. 424,018 filed January 28, 1930 (of which this application is a division) and has 5 for its object to provide apparatus of simplified construction and more eliicient than used heretofore. Y y v Y In the present invention'the liquid fuel is supplied to the burner under pressure, the

lo pressure being obtainedeither by pneumatic or hydraulic means'. j c j j.

The stove or heating portion of the apparatus has a hot plate provided with a-number of openings, and between the openings are,

arranged `projections extending upwards each projection being preferably conical and of the same height. The base of the utensil or apparatus to be heated is provided with a series of depending projections each arranged vertically over an opening inthe hot plate, positioning lugs or flanges being provided on the receptacle or the hot plate so as to ensure each depending lug-being opposite a perforation in the hot plate and therefore depending into the diffused ame of the burner` and so forming anV annular heating space for the hot gases, as well as considerably increasing the heating surfaces.

In order that the invention may be the more clearly understood reference will now be made to the accompanying drawing,

whereinr- Figure 1 is a sectional elevation of the apparatus and i Figure 2 is a plan view thereof, while Y Figure 3 is a plan of one form ofvbase portion of the utensil. j

In the hot plate B are provided flame holes B1 arranged between upwardly extending tapered projections B2. On these projections rest a utensil C having a detachable base piece C1 provided with depending projections C2 arranged to be substantially coaxial with the flame holes B1 and so as to form an annular flame space around each projection C2. Around ythe side of the base Cl are provided lugs or broken rings C3 for positioning the utensil with C lon the hot plate B. The base C1 of the utensil C is detachably fixed on a conical base C4 by means War lflame yspace above the ame hole.

a ring kkC5 havinglan inner inclined pori tion corresponding to theV conicalportion C4 three `sections'Gll,v C15, C16, eachsof which of theutensil Cf kThe ring C5 is divided into A1, A2-,fana Aa which are 'arranged hori-Y p zontally vand so that the' flametherefrom will,` be bent 'upwardsand passthroughthe Haine u holes ABlY inv the hot plate B. VBeneath the `Vlame andV supported by or `forming part of the standard B3 is a casing B4 curved 'up`- sj' to correspondfwiththe'shape of the Hallie.l
